Change log

Features 🏎️

  • milestone!48 - Add TurboQuant quantization variant, 8x vector compression without the recall tax
  • https://github.com/qdrant/qdrant/pull/8605 - Add API to create and delete named vectors in existing collection
  • https://github.com/qdrant/qdrant/pull/8606 - Deep memory reporting, show memory usage breakdown for storage components
  • https://github.com/qdrant/qdrant/pull/8714 - Add low memory mode, force open everything on disk to minimize out of memory crash on startup
  • https://github.com/qdrant/qdrant/pull/8715 - Add strict mode parameter to reject updates when memory usage is high (max_resident_memory_percent)

Improvements 📏

  • https://github.com/qdrant/qdrant/pull/8790, https://github.com/qdrant/qdrant/pull/8769 - Use dynamic CPU pool for search workers, improve search performance when there's high IO wait
  • https://github.com/qdrant/qdrant/pull/8526, https://github.com/qdrant/qdrant/pull/8656 - Use operation size based batching in shard transfers to achieve higher throughput

  • https://github.com/qdrant/qdrant/pull/8767 - When collection update triggers optimizer recreation, clear any optimizer errors to allow recovery without restart
  • https://github.com/qdrant/qdrant/pull/8784 - Use snapshot based shard transfers for much faster recovery if WAL delta cannot be resolved
  • https://github.com/qdrant/qdrant/pull/8782 - On snapshot transfer, first clear shard data on receiver to prevent out of disk crash
  • https://github.com/qdrant/qdrant/pull/8689 - Clean temporary directories before loading collections, may prevent out of disk crash on recovery
  • https://github.com/qdrant/qdrant/pull/8830 - Don't hold shard holder lock during search to prevent blocking various other operations
